    I wonder how they calculated the range. If it’s representative of the real world drive cycle these will experience, the estimate might not be too far off. A postal route is constant low speed stop and go. Regen is much more effective at higher speeds, so they’re probably dumping most of their kenetic energy to hear via friction brakes. Suspect their drive cycle is going to be something like an endless cycle of 25 kw acceleration, rest, 25 kw acceleration, rest, etc.

      I bet it’s this exactly. Cars get more efficient metrics on highway vs city start and stop. If the vehicle ONLY starts and stops it must be terrible, even if these have regen brakes.
